ings accompanying and forming a part of the same.

This invention relates generally to signal apparatus in which a personat a glven point or station can'cause a ortion, normally in aninoperable condition, to move or be put into an operable condition and asignal to be given by the movement of a car or similar moving object asit approaches a given point and to restore the parts to their normalcondition.

Among the objects of the present invention are the provision of anapparatus or signal system which is simple, practical and eliicicnt ascompared with prior devices, and

5 one of the other objects is to improve generally the principles ofoperation of the system and parts thereof.

operable one, where either signal can be given to the full extentdesired and such parts may be restored to positions corre' sponding tothose seen in Fig. 4 and the circuits be put into an inoperablecondition; Fig. 6 is a side view of the devices for three differentcircuits and signals, as seen in Fig. 2, but on an enlarged scale andwith some of the parts in ditl'erent positions from what correspondingpartare seen in Fig. 2; Fig. 6 shows diti'erent means for movin themovable portion of the carriage into and out of actuating position fromwhat is shown in preceding figures; Fig. 7, shows, on an enlarged scale,part of one of the switch devices seen in Fig. 6, with portions of someof the parts broken away to better illustrate certain features ofconstruction; Fig. 8 shows the bottom portion of what is shown in Fig.7, but turned one quarter around with that which is broken away in Fig.7 shown in full; Fig. 9 is a top view, part] in section, of a portion ofone of the swito devices seen in Fig. 6, but on the scale seen in Figs.7 and 8, illustrating the manner of mounting the movable parts on theirsupports and of the two arm springs which normally hold such parts inposition to be actuated by the means provided for this purpose; Figv 10shows a different form of means connecting the movable portion of thecarriage to the armature of the electromagnet by which such portion orportions are moved into their active positions relatively to the movableparts with which they engage and which are there mounted on supports;Fig. 11 shows in front view portions of a somewhat different embodimentof the present invention from what is shown in preceding figures. thesignal devices. circuits and means by which the signals are given andthe circuits are brought from an inoperable to an. operable conditionbeing diagramunitically shown; Fig. 12 shows in cross section and on anenlarged scale portions of one controller. the means by which it ismoved into position for bringing the circuit or circuits into anoperable condition seen at the lower left hand portion of Fig. 11. andwith the parts in the positions they occupy when the ei"cuit or circuitsare in an inoperable condition: Fig. 13 illustrates one of the movableparts. the two arm spring by which it is normally held in position onits mounting, and its relation to one of the terminals of the circuitwhen such circuit is brought from an inoperable to an operablecondition; Fig. 14 shows a modified manner of mounting the two terminalsof a circuit which are to be closed by the movable part mounted on itsfixed support; and Fig. 15 shows a construction wherein two movableparts mounted on a single fixed support and two separate switch devicesare actuated, one by each of the two movably mounted parts.

In Figs. 1 to 9, inclusive, one embodiment of the present invention isillustrated and wherein each circuit closing or switch device isprovided with a support or controller, which is spring actuated in onedirection, that is, as here shown, in the opening direction. As hereshown the opening direction is the direction the controller or supportor supports move to bring the circuit or circuits into an inoperablecondition, that is, a condition where the circuit closing devices areout of operative relation with the parts which ccact therewith to closethe circuits to give the designed signals. Also, as here shown, two ofthese individual circuit closing or switch devices are so connectedtogether that both are acted upon by one means to bring such devicesinto operative relation with their coacting devices and both may bereturned to their inoperative relations to such devices uponeithersignal being actuated, that is, by the actuating devices which firstreach the actuating position to actuate either one of such devices,close the circuit and give the particular signal. Any number of suchcircuit closing or switch devices may be thus connected together that isdesired, or there may be only a single one used, as for instance, whenonly a single car or similar moving object is to be signaled. There maybe two of such circuit closing or switch devices for each car, or otherobject, at each floor or station, except the first and last, from whichsignals are to be given or received. One of these devices is for givingsignals as such car or object moves in one direction and the other as itmoves in the other direction, and for convenience may be designated asup devices, for up signals, and down devices, for down signals. As manyof the up devices for any given floor or station, one for each car orobject to be served, may be connected together as one desires and whenconnected together, as shown, they may be, actuated or moved into theoperable condition or relation by the use of a single push buttondevice, of ordinary construction, and clectromagnet, as indicated inFig. 2, where electromagnets are seen connected with push buttondevices, there being one push button for each floor or staticnfor upsignals and one for down signals, which are to be served and from whichsignals are to be given, by the use of such devices. Also, as shown,each circuit closing or switch device is provided'with a'retainingdevice to hold or retain the same in operative relation to the movablecoacting parts, by which the circuits are closed, until it is desired toreturn or restore such devices to an inoperable relation to such partsand ren der them inoperable bv the designed movement of such parts, whensuch retaining devices arc actuated by suitable means and the circuit orcircuits are restored to an inoperable condition. As here shown two ofthese retaining devices are connected together in such manner that uponactuating one the other is actuated and both of the switch devices arerestored to their inoperative relations to'their coacting parts. Theremay be as many of these retaining devices as there are switch or circuitclosing devices, thus or otherwise connected together, so long as theyare operable to retain such devices in position to close their circuits,as hereinafter described, and to restore such circuits to an inoperablecondition. These individual supports or controllers for the circuitclosing or switch devices and retaining devices thus shown are morefully set forth in an application filed contemporaneously herewith.

As shown in Figs. 1 to 9, inclusive, each support or controller carriestwo pairs of contact springs or terminals, one pair for one circuit andthe other pair for another circuit,,t-he two pairs being insulated fromeach other, but they may have a common source of energy, as iswellknown. If desired there may be a single pair of terminals for asingle circuit or a single terminal of a pair carried by the controller,accordingly as one chooses to arrange the circuits to render theminoperative or operative. So long as each controller or support carriesone terminal of a circuit such terminal may be moved into and out ofoperative relation to thecoacting parts and the other terminal of thatcircuit and such circuit be brought into or out of operative condition,or into or out of condition where their respective signals may or maynot be iven.

Fig. 1 diagrammatically illustrates the arrangement of the switch orcircuit closing devices, the circuits connecting such devices to thesource of energv for two cars or similar objects, there being eightfloors of a building, or stations indicated, two series of stationsignals for each car. and a signal in each car. One series of stationsignals are for up signals with which the up" devices are connected andanother series with which the down devices are connected in each car.The same signal device is employed in the car to give signals in boththe up and down directions. The switch devices are represented by smalldots, one dot for each terminal of each circuit, and hence four dotsrepresent one of the switch or circuit closin devices seen in Figs. '2,3, &c. A, A, A, &c., represent the up and A, A, A, A, &c., represent thedown signal switch devices of each of the two cars, as they are the samein each case. Each switch device has two pairs of terminals designated,as follows: for switch device A, the pair for the station signal as aand for the car signal as a, device A, the pair for the station signalas a and the pair for the car signal as a", and so on and device A, theair for the car s gnal as a, and the pair or the station signal as a,and device A, the pair for the car signal as a and the pair for thestation signal as a, and so on. For clearness of illustration the switchdevices for car H have the pairs of terminals designated and for car Hthe designating characters of the devices themselves are used, and it isto be understood that the switch devices and pairs of terminals for thetwo cars are duplicates of one another. These switch devices arediagrammatically shown in Fig. 1 and the manner of arranging themrelatively to one another and the other parts is seen in Fig. 2. Only apart of them are fully shown in Fig. 2, the others being indicated bylines inclosing rectangular spaces, the better to show this arrangementof the devices relatively to the arts which serve to close the circuits.nly one of each pair of terminals is fully seen in this Fig. 2, as it isa front elevation and the other member of each pair is underneath theone shown, as indicated in Fig. 3. As shown in Fig. 2 there are twocarriages B and B. Carriage B, Fig. 1, is connected with the actuatingmechanism J of car H and carriage B is connected with the actuatingmechanism J of car H, by any well known speed reducing mechanism, andsuitable flexible or other connections, as j and 7', so that suchcarriages and the switch devices may be placed in any con venientlocation desired, and each carriage will move accordingly as the carmoves with which it is connected, the switch devices being arranged atthe proper intervals in the path of movement of the carriage to give thesignals at the desired points in such path, as for instance wherestations or floors are located. Each switch device consists ofa suitableframe or support N,

Fi 7, in which is mounted a controller n,

which is movable in two directions and carries one or more terminals ofone or more circuits, and means by which the controller is moved. Asshown, the controller n, is actuatedin one direction b a spring 11 andis actuated in the other direction by an elbow lever, as h or k, 4 and5, connectin therewith, which lever is in turn connecte with anarmature, as m. or m. This armature is attracted by an electroma 'pairseen, but not shown.

et which is to be energized in any desire manner. The spring nconstantly tends, when arranged as here shown, to move the controllerinto the position where the terminal or terminals of the circuit orcircuits will be in an inoperable position. The elbow lever has toovercome the stress of this spring n, when the controller is actuated inthe other direction. This spring, n, at one end rests against theshoulder formed on controller n and at the other end against the frame Nand, hence, the stress of this spring tends to move the controller intothe position seen in Fig. 7, which is the position where the two airs ofterminals are out of o rative relations with their coacting partsesigned to bring each air into contact and thereby close the circuit orcircuits and give the signal or signals. This controller is reduced insize at the end where spring n goes, as shown, and enters a roundopening in a rtion of the frame N, so as to move there- 1n. At the otherend of this frame two cars N, N are formed, as more clearly seen in Fig.8, between which the other end of the controller is received and it isheld between such ears by the slot n, in that end of the controller, andpin n passing through the ears N N, as indicated in Figs. 7, 8 and 9. Tothis controller there is attached a piece of insulating material, as n,Fig. 6, upon which is mounted the two pairs of terminals or contactsprings, as indicated in Figs. 2 and 3, one pair of which is seen inFig. 6 and is there designated as a", the other pair for that devicebein back of the 0 frame N there is pivoted an elbow lever h, moreclearly seen as h in Fig. 5, or as h in Fig. 4, having a slot n in oneend, which ongages with a pin n fixed on controller n. The other end ofthis elbow lever is is pivotally attached to a link is, which in turn isattached to an armature m of electromagnet M, Figs. 2 and 5. In Fig. 4two of these elbow levers h are shown as pivotally attached to link b,so that both move at the same time by moving link h by armature m. Thesprings n, Fig. 7, one of which is also seen in Fig. 4, tends to holdthe link It in the position there seen and this link is moved againstthe stress of these springs n from the positions seen in Fig. 4 to thosecorresponding to that seen in Fig. 5 by energizing magnet M. In Fig. 5the parts are seen in the position they occupy when magnet M isenergized. Thus the spring n, the elbow lever h, its connection. witharmature m, this armature and electromagnet, form means by which thecontroller is moved in two directions, and the elbow lever h, with itsconnection with the controller n are the means by which theelectromagnet and armature operate such controller. Also the link Iiconnects similar portions of the operating means oftwo correspondingswitch devices together, so that the electromagnet and its armature moveboth controllers together or at the same time. When the parts occupy thepositions seen in Fig. 5 the terminals or contact springs are inoperative relation to their coacting parts, as C Fig. 7 or C Fi 6, andwhenever these parts C or C, whic are pivotally mounted on frames N ofthe switch devices, are moved on their pivots, as is the case of devicesA and A, Fig. 6, then such terminals or contact springs will be broughtinto contact and the circuits closed. as in the case of device A, andthe signals 'ven. In Fig. 6 controller 11. of switch evice A is in theposition seen in Fig. 7 and hence the contact springs remain separatedor open, as pair a are there seen. The controller of switch device A isin the position in which controllers n are seen in ig. 5, after elbowlevers h and link It have been moved and the corresponding terminals orsprings are in contact, as shown. The extent of movement of controller nand its terminals or contact springs from one position to another tobring the circuit or circuits from an inoperable to an operablecondition is seen in the case of device A of Fig. 6, where thecontroller has been actuated, but the coactin parts C and C have not yetbeen actuatef. The difference in ositions between the dotted and fulllines indicate the extent of this movement. The extent of this movementof the controllers, as n, may be such as is desired so that when thecontrollers and attached parts of the switch devices are in aninoperable condition the movement of the parts, as C and C will notcause one terminal to electrically connect with the other. As seen inFig. 6 actuating device or carriage B is moving in the direction of thearrow and has not yet quite reached parts 0 and C, part C only beingseen, and the terminals or contact springs are open and will remain 0 enuntil the actuating device or carriage as actuated parts 0 and C, asseen in the case of switch device A.

As here shown, when the magnets M, M, &c., are energized and thecontrollers are actuated, retaining devices are employed to hold orretain the controllers and their connected circuits in substantially theposition shown in Fig. 5 and of devices A and A of Fig. 6. Theseretaining devices consist of elbow levers O ivotally mounted on frame N,as more clear y seen In Fig. 4, where such devices are in their normalositions ready to engage with pins 0 fixed in controller n. One end ofelbow lever O is hook shaped, so that as controllers n move toward thepivot of such elbow levers the spring q causes such levers, through linkp, to press against the pins 0 and as soon as such controllers havemoved far enough in that direction such spring causes the levers to engage with pins 0, as seen in Fig. 5, where the two correspondingcontrollers are held by corresponding retaining devices connectedtogether to act or move as one, so that-either actuating device orcarriage, (the one first approaching,) can actuate both retainin devicesat the same time. The springs q, q &c., normally tend to move theretaining devices into the engaging position and to re tain thecontrollers and circuits in position for the circuits to be closed andthe signals to be given, when once brou ht into a condition or positionwhere this can be done. As shown the frame or support N of each switchdevice has a retaining device pivotally attached thereto, and theretaining devices of two corresponding switch devices are connectedtogether so that the actuating device of either one of two cars mayactuate both of the retaining devices. These levers O, O, &c., areactuated against the stress of the springs q, g, &c., by projectionsmounted on the carriages, one projection on each carria e for up signalsand one on each for own signals, and such projections engage with theelbow levers O, O, &c., and actuate them at the time it is desired thatthe signals shall cease, or otherwise, as one sees fit to construct theapparatus. It will thus be seen that the circuits are brought intooperable condition upon energizing the magnets M, M, &c., in any wellknown manner, as by push button devices arranged at the desiredstations, and that such circuits are restored to an inoperable conditionby the actuation of the retaining devices by the projections carried bythe carriages, as such carriages move past the retaining devices inaccordance with the movements of their respective cars, whether there beone, two or more cars. to be served. As seen in Fig. 2 switch devicesfor eight stations or floors are indicated, but there are only retainingdevices and controllers and switch actuating devices shown for portionsof four stations or floors, the first and last up, and also the firstand sixth down stations for two cars. As before explained this requiresfour electromagnets and means for energizing them. Magnets M. M, M andM, respectively. Magnets M M actuate the switch devices for one floor orstation for two cars, one magnet. as M, actuating the up devices forthat floor or station and the other magnet, as M, actuates the downdevices. The means for energizing these magnets are shown locatedadjacent to each other at one point or place and as seen in Fig. 2, oneis placed over the other somewhat as would be done in practice. Usuallythe push button actuating means for causing the signals to be given inthe up ward direction is arranged immediately over the device forcausing signals to be given in a downward direction. The means forenergizing magnets M and M are laced at different points. Forconvenienceo illustration difl'erent sources of energy are shown, but inpractice a. single source would naturally be used. Push button devicesare illustrated but any form of devices may be emloyed. Push buttondevices P, P, P and are shown with sources of energy S, S and S. MagnetM is connected with push button P and source S by wires 66, 67 and 68.Magnet M is connected with push button P and source S by wires (39, 70,68 and 71. Magnet M is connected with ush button P and source S by wires72, 3 and 74 and magnet M is connected with push button P and source Sby wires 75, 76 and 77.

The levers or coacting movable parts C and G are, as shown in Fig. 9,mounted on a common support or stud l), which in turn is fixedly mountedin frames N of the switch device, as shown. Lever or movable part C hasahub c which receives a two arm spring (1 and lever or movable part C hasa similar hub c, which receives a similar spring at, which springs arearranged to exert their stress in retaining and holding these levers ormovable parts to the position indicated in Fig. 7. Stud or support isprovided with a projection d with which spring 03 engages, one arm ofthe spring engaging with one portion of such pro ection and the otherarm engaging with the opposite portion. This pro ection (1 permits thetwo arms of this spring 03 to separate or move apart from one anotherand the stress of the spring holds both arms in contact with projectiond when force is not applied to overcome such stress. On the other orreduced end 0 of support or stud D a sleeved with a projection d similarin construction "and function as projection d is secured by nut d, whichfixedly holds sleeve 0 from turning on the reduced end 0 of support D.This sleeve 0" also holds the levers or movable parts 0 and (l in placeon stud or support D, leaving them free to turn thereon as occasionrequires. Each lever or movable part C and C is, as shown, provided withan arm or extension C and C respectively. Each of these arms orextensions is provided with a pin or projection c and 0 respectively,which pin engages with the two arms of each of the springs d and d,respectively, as shown, Figs. 7 and 9, more particularly. Each of theselevers or movable parts C and C is also preferably provided at one endwith insulating material 0, Fig. 7, to contact with the adjacentterminal or contact spring and at the opposite end with a roller orwheel 0 with which the coacting portion orportions of the carriage orcarriages engage to bring the terminals or contact springs into contactto close the circuit or circuits, as seen in the case of switch device Ain. Fig. 6, where the parts are shown in the positions they occupy atthat time. These levers or movable parts 0 and C are free to move inboth directions except for the stress of the springs d and d,consequently the engaging parts carried on the carriage, if fixedlyattached thereto, may move or operate them in either direction ofmovement. When these levers are moved in one direction the insulated endportions, as 0, move toward the contactsprings or terminals and whenthey move in the other direction such ends move in the oppositedirection and away from such terminals and do not affect them, even whenin position to be actuated by such levers.

Each carriage is mounted in grooved rollers, as b, b, 0, b, &c., so asto move over the switch devices, as indicated in Figs. 1 and 2, and indefinite relation thereto and the levers or movably mounted parts, as (Jand U, and to co-act therewith, as hereinafter explained. 7

Each actuating device or carriage, B, or B, as here shown, is preferablyprovided with parts, as E, E, to co-act with the levers, as C and C,which are movably mounted thereon, as shown, one part to coact with thelevers for the up switch devices and another to co-act with the leversfor the down switch devices, carriage B having parts .E and E andcarriage B having parts E and E parts E and E coacting with the upswitch devices and parts E and E co-acting with down switch devices.These parts, as E, E, E, &c., are preferably mounted on swinging links,as e, e, e &c., one end of each link being pivotally mounted on asupport carried by the carriage and the other ends being pivotallyattached to such parts, two links for each part, as shown, moreparticularly, in Figs. 2, 3 and 6. Links e, e, 2 &c., are connected withsupports F, F, F etc, respectively, and as a result parts or portions E,E, &c., are free to swing back and forth thereon except when restrainedtherefrom. These swinging portions of the. actuating device or carriagemechanism are mo\ ed in one direction, that is, away from the lovers orparts C and C by springs f, 7'', &c., res )ectively, and they are movedin the other direction, that is, toward and into position to engage withthe rollers, as c on the levers or movable parts 0 or C byelectromagnets, L, L, L &c., armatures I, l, P, &c., and connectedparts, when the magnets are energized, and such parts are held in suchpositions so long as such magnets remain energized, the force of themagnets overcoming the stress of springs f, f, F, &c. The armatnres Z,l, l, &c., are mounted on pivoted levers l, l, l, &c., re-

spectively, as shown, the opposite ends of which are pivotally connectedwith portions E, E, E, &c., respectively, so that as such armatures areattracted by the magnets the levers l, l, l, &c., turn on their fulcrumsmoving the parts E, E, E, &c., respectively, into the position, in whichportion or part E is seen in Fig. 6, which has been moved from theposition seen in Fig. 3 to that seen in Fig. 6, or from the positionseen in dotted lines to that seen in full lihes in Fig. 6. As thus seenthe links are substantially at right angles to the under or co-actingsurface of the part E. This is the preferred manner of arranging thelinks, if these parts be mounted as ust described, but they may be.arranged otherwise, if desired; also the links may be dispensed withand the portions of the carriage mechanism which coact with the levers,as C or C, may be otherwise mounted to move into and out of active orcoacting relations with such levers,

as, for instance, by pins and inclined slots as indicated in Fig. 6. Asthere shown actuating device or carriage B" 18 provided with co-actingpart E" in which slots e? and e are formed which embrace pins e and 0",respectively so that as this part E is moved from the position seen infull lines to that seen in dotted lines the inclined slots acting onpins e and e move such part E away from the rollers c on movable parts Cto the extent indicated by the dotted lines, when the parts or levers Cmove into the positions seen in dotted lines by the action of their twoarmed springs d. One advantage of the links is that they may be made ofsubstantially the same length between centers as the distance from thecenter of the hub c of lever C to the outermost part of roller'c, andthen if the part or portion E be brought into co-acting relations withlevers, as C and C, while directly over the rollers, as a, such portionE will move into position with a movement substantially correspondingwith the movement of the levers, as C and C, on their studs D andwithout undue strain upon any of the parts of the mechanism. Thesprings, f, f 112:, &c., always tend to move the ortions E, E, &c., outof coacting relation with levers as C and C, and are of the desiredstress to do this work and hence, when the magnets L, L, L, &c., are notenergized all of these portions are held by these springs in theinactive positions and remain so until the stress of the springs isovercome by a superior force. The stress of each spring in theconstruction shown, is overcome by energizing a magnet as L, L, &c. Thisis accomplished in any well known manner, but it is preferably done bvmeans of an automatic switch as K or K. Fig. 1, combined with circuits,&c.. so that as the carriage changes its direction of movement the uut0-matic switch changes cuttin out one magnet and cutting in anot er.switches K and K may be of any desired form and construction, so long asthey operate to cut out and cut in their res tive magnets at the desiredchanges in t 0 direction of movement of the actuating devices orcarriages with which such magnets are connected. Such switches arediagrammatically shown in Fig. 1 and as there seen, they are suitablyconnected by friction or otherwise with some moving part of the caractuating mechanism so that as the car reverses its direction ofmovement the switch is operated and stays operated until the nextreversal takes lace and so on. Each switch, as indicated: arms, as k, kand Is, is, Fig. 1, which are connected together and to the moving partof the actuating mechanism by connections, as k and k. These switch armsconnect with switch points, as In, k for switch K and k", k for switchK. As shown switch arm is is out of contact with switch point k andswitch arm k is in contact with switch point Is. Also switch arm is isin contact withpoint k and arm k is out of contact with point la.

The magnets L, L, &c., may be energized from any desired source ofsuitable character. As shown in Fig. 1 they are energized from the samesource that operates the signal devices. When this is done the magnetsare to be suitably formed or artificial resistance is to be added toprevent undue heating under long continued use, as is well known. Asshown artificial or additional resistance is employed, as R, R, &c., andeach is proportioned to its respective magnet or magnets which it is toserve.

The circuits between the source S and the automatic switches and magnetsand back again are as follows: A wire 1 leads from source S to arms I:and k of switch K. As

before explained switch arm 1c is in contact with point Is and thecircuit proceeds from such point by wire 2 to resistance R and thence bywire 3 to magnet L on carriage B, and H in car H and thence by wire 5 towire 6 and the other side of source S. When the automatic switch K isshifted from the position shown to one where arm k is in contact withpoint is and arm k is out of contact with point k the circuit is fromsource S by wire 1 to arm k, point In", wire 7 thence to resistance R,wire 8 to magnet L and by wire 9 to wire 4, thence to switch H in car Hand from there by wires 5 and 6 to the other side of source S. From thisit will be seen that the circuits for magnets L and L of carriage B passthrough switch H in car H and also that such circuits pass throughautomatic switch K before reaching switch H.. From this it results,first, that These has two switch from thence by wire 4 to the switchonly one circuit through one of the magnets is closed at a time, by theautomatic switch K, the other being open, and second, that both circuitsare, as shown, closed through switch H and remain closed until suchswitch is opened, when both circuits are gpen and neither magnet can beenergized.

enee the operator in the car, by opening switch H, can prevent bothmagnets L and L from being energized and as a result the movableportions of the carriage mechanism, which co-act with the movable arts,as C or C, to close the switch termina 5 remain in the inactivepositions, that is, out of co-acting relations with the switch devicesof that carriage, and no signals will be iven and the movements ofcarriage B baci and forth do not atfect the apparatus in any way. If forany reason it is desired that car H be run without giving signals it isonl necessary to open switch H and leave it open until such time as thesignals are to be again iven, when switch H can be closed and t e aparatus be made to operate as before. Qt er switches may be p aced ineither of wires 4 or 5 if desired, in the same manner as switch isplaced, or in any other well known manner.

The circuits for magnets L and L of carriage B are as follows: fromsource S by wire 10 to wire 11, thence to arm k of automatic switch Kand oint k, (when switch K is in the position shown,) and thence toresistance R by wire 12, thence by wire 13 to magnet L, and thence bywire 14 to switch H in car H and from thence by wire 15 to wire 6 andthe other side of source S. When automatic switch K is actuated by areversal in the direction of movement of car H and carriage B thecircuit for magnet L is as follows: arm is is in connection by wire 11with source S and point Is and a wire 16 leads from such point toresistance R, thence, by wire 17, to magnet L and thence by wire 18 towire 14, switch H in car H and from there b wires 15 and 6 to the otherside of source As before explained each station or floor is providedwith two signal devices one up and one down, and, as shown in Fig. 1,these are designated as I, I, I, &c., for giving signals as the carmoves upwardly and as I, I, I, &c., for giving signals as the car movesdownwardly, the signals for each car being duplicates of those for eachof the other cars served by the apparatus and each car and connectedcarriage operate only their own individual signa is.

Also each car is provided with a sin le signal device, as G, for car H,and G or car H which signal devices are operated by the movements of thecar and connected carriage as the car or object reaches the desiredpoint. station or floor where the s gnal s to be given. As shown thereare eight stations or floors where signals are to be given by each car,but there may be any desired number in any given apparatus. Also eachstation has two switch devices assigned to it,

one for up signals and one for down signals, each device having two airsof terminals or contact sprin s by wiiich the circuits are closed. Assiown in Fig. 1 only the circuits leading to switch devices of everyother station or floor are shown, this being done to avoid confusionfrom a too great multiplicity of lines and as the circuits are all ofthe same kind or character, illustrating one is in substance anillustration of all of the others, to those skilled in this art. The upswitch devices for one car constitute a series and for two or more carsa plurality of series. 'The up switch devices for two or more cars forany given floor or station correspond one with the other in that eachserves its own car at one floor or station and does the same work andgives a similar signal when the circuit is closed. This is also the casewith the down switch devices at any given floor or station served by twoor more cars.

The circuit or circuits for car H are as follows: A wire 1 leads fromsource S and connects with wire 19, which leads to signal G in car H andfrom thence a wire '20 connects with wire 21, which is connected withterminal a of switch device A, and then with terminal a" of switchdevice A, and so on until the last pair of terminals is reached, theother terminal of each pair being in turn connected with wire 22, whichconnects with wire 6 and the other side of source S. As thus connectedthe circuit may be from source S through wires 1 and 19 to signal G andthen by wires 20 and 21 to any pair of terminals connected with wires 21and 22, through such terminals (when brought into contact,) to wire 6and back to source S. This is for the car H and carriages B as they moveupwardly; when they move downwardly the circuits are the same as whenmoving upwardly to the point where wire 20 connects with wire 21, whichalso connects with wire 23, which latter wire connects with one of eachpair of terminals of switch devices A, A, &c., as wire 21 does withthose of devices, A, A, &c., the opposite or other terminal of each paircon necting with wire 24. as wire 22 connects with the terminals of theup devices.

For car H the circuits are as follows: A wire 10 leads from source S andconnects with wire 11, which in turn connects with wire 25 leading tosignal G in car H and a wire 26 leads from there to and connects withone of the terminals of switch devices A. A. &c., (the up switch devicesfor car H'.) as wire 21 connected with corresponding terminals of the updevices for car H,

88 49, which connects #6 rolpondingsignals for carH were connecttheopposite or other terminal of each of such pairs being connected with awire 27 which connects with wire 6, which in turn connects with theother side of source S. As in the case of car H the circuit or circuitsfor the down going signals are the same for a given distance, to thepoint where wire 26 connects with wire 28, which in turn connects withthe terminals of switch devices A, A, &c., as wire 23 connects withcorresponding terminals of corresponding switch devices for car H, theother or opposite terminals of each switch device being connected withwire 29, which in turn connects with wire 6 leading back to source S.

The circuits for the station signals forcar H are as follows: A wire 30leads from source S and connects with each signal device at eachstation, that is, such wire is common to all of such devices, fromsignal I, (the upper one of the up signals,) a wire 31 connects with oneof the pair of terminals, as a, of switch device A, the other terminalof such pair being connected by wire 32 with wire 1, which leads to theother side of source S; from signal I wire 33 connects with one of theair a, of terminals of. switch device A, e other terminal beingconnected by wire 34 with wire 1 and source S, as before; from signal Iwire 35 connects with one of the air a'-o terminals of switch device A,t e other terminal being connected by wire 36 with wire 1 and source S;and from signal I wire 37 con- .nects with terminal a of its respectiveswitch device A, which is seen in Fig. 2, the other terminal beingconnected by wire 38 with wire 1 and source S, as before. For the downsignals 1, I, &c., a wire 39 connects with wire 30 leadin from source Sand also connects with elf of the down signals for car H as wire 30connects with the up signals; from signals I I, I", and 1", wires 40,42, 44 and 46, respectively, con nect with one of the down pair ofstation terminals of switch devices A, A, A and A, respectively, as inthe case of the up pairs, the opposite or other terminal of each pairbeing connected by wires 41, 43, 45 and 47, respectively with wire 48,which in turn is connected with wire 10 and source S.

The down signals for car H are all connected with source S by wire 6 andthe up signals are also thus connected by wire with wire 6. The upsignals I, I, I and I are connected with corresponding terminals ofswitch devices for car H, as corresponding signals for car H areconnected, using wires 50, 52, 54 and 56, respectively, instead of wires31, 33, 35 and 37, res tively, as in case of car H. The down signals forcar H as I, I, I" and I" are connected with the terminals of switchdevices A, A, A and A, as cored, using wires 59, 61, 63 and 65-,respectively, instead of wires 40, 42, 44 and 46, re spectively, as incase of car H. The respective opposite or other terminals 'of such updevices are connected with wire 27 by wires 51, 53, 55 and 57,respectively, and the respective down devices are connected with wire 10by wires 58, 60, 62 and 64, respectivcl The operation of the apparatus,as thus shown, is as follows: Assuming that a person is on the floor orat the station where push button devices P and P, Fig. 2, are locatedand desires to go upwardly therefrom, (it being understood that theremay be as many. stations or floors above and below those shown in Figs.1- and 2, as one desires,) he would press the push button P, energizemagnet M move the controllers of switch devices A, A, into positionwhere retaining devices 0, 0, would engage therewith and retain suchcontrollers and the terminals of the circuits mounted on suchcontrollers in position until actuating device or carriage B had reachedswitch device A with whichthat carriage co-acts when si nal I, locatedat that station and signal in car H for that car would be operated andthe signals, in themovement of the carriage, would be given at bothplaces, and continue until projection e on portion E of carriage B,Figs. 2 and 4, reaches retaining device 0 when the outer end, b thecontinued movement of carriage will be moved downwardly and its hookedend, in engagement with pin a, will be moved out of engagement therewithand by reason of link p the corresponding retaining device for switchdevice A of the other car B, will be correspondingly moved and thecontrollers of both switch devices A, A, will be free to move under thestress of their springs n and the terminals of both switch devices bemoved awa from co-acting relations with portions and E of carriages Band B and the signals I and G will cease to be operated and the circuitsconnected with such switch devices will be restored to an inoperablecondition, until push button be again actuated, when the operation maybe repeated. The operation of each of the other stations is a repetitionof the above, there being separate up and down 'push button devices tobe actuated for each of the stations or floors where persons are to goboth up and down, as is well understood in the art.

It is to be observed that by reason of the springs a, g, &c., theretaining devices are ever ready to engage with pins 0, o, &c., 'of thecontrollers n and, therefore, just as soon as the armature of any of themag nets as M, M, &c., has been fully attracted the retaining devicesfor the controllers connected with such armature engage therewith andretain them in position permittin such magnet to be denergized withoutanger of the controllers and terminals returning to the positions fromwhich they were moved upon the energizetion of such ma net. Hence amomentary ener zation of t e magnets, as M, M, &c., is al that isrequired to brin the circuits from an inoperable to an opera lecondition, and when once brought into an operable condition the remainin this state until the retaining evices are operated by the movement ofthe carriage or carriages.

If for any reason it should be desirable for the movable co-acting part,as E, of the carriage or actuating device B to move on its links andaway from the levers or movable parts, as C and C, as for instance onthe sudden reverse movement of the carriage and before the automaticswitch had reversed and cut out the magnet L a yielding connectionbetween such part E and the lever l to which armature l is secured maybe made, as shown in Fig. 10. As here shown actuating device or carriageB carries the movable co-acting portion or part E by means such as shownin Figs. 2, 3 and 6. The carriage B is also provided with a magnet L,armature Z, pivoted lever l, to which armature l" is attached and springf by which the lever is moved to move the armature away from its magnetL. The stress of this spring f is of course overcome by the action ofthe magnet upon its armature. Pivoted lever l" is made in two parts Iand Z. This part Z of lever Z" is in the form of a flat spring securedto lever portion l at one end, as shown, so that upon the application offorce to coacting part E in a direction tending to move it from theposition seen in Fig. 10 in full lines to that seen in dotted lines thisspringy portion 1" will yield and permit part and the pin 1" fixedthereto-to move and swing on its links in the opposite direction to thatin which it swings under the stress of spring f when magnet L isdeenergized and in so doing to move away from the levers or movableparts, as C and C, and then when the force thus applied is released orthe magnet L is deenergized the parts of lever Z assume the positionsshown in full lines.

Instead of the construction of movable parts, switch devices,controllers and retainlng devices seen in the preceding figures aconstruction like that seen in Figs. 11 to 15 may be employed, whereineach controller is shown in the form of a bar, sliding horizontally and,if desired, supporting switch devices for a plurality of actuatingdevices or carriages to co-act with: also wherein such controllers areretained or held in the positions which renders the circuits connectedtherewith inoperable and the controllers are spring actuated intoposition to bring the circuits into operable condition and areyieldingly held there by the stress of the springs which actuate them.In the construction shown in these latter figures, as in that seen inthe preceding ones, the parts which bring the terminals of the switchdevices into contact to close the circuits are movably mounted onsupports and they may always be in position to be actuated by themovements of their respective carriages. In both constructions thesemovable parts are preferably held in position to be actuated in eitherof two directions, as the carriage moves into engagements therewith, andthis is preferably done by means of two arm springs, as shown. In theconstruction s own in these Figs. 11 to 15 two bars or controllers maybe employed for each station or floor. Controllers, switch devices,movable parts, &c., are shown in Fig. 11 for two of such stations orfloors and somewhat widely separated from one another. In practice thespace between these two sets of devices, one set for each station orfloor, would be occupied by similar sets of devices, which are hereomitted for clearness of illustration. Also as many similar sets ofdevices may be arranged above and below those shown as the constructorsees fit to employ to serve any desired number of stations or floors.Also as shown the ap aratus is arranged to serve two cars, each 0 whichis provided with a signal device, which are the only signals theapparatus, as shown, is designed to give. If desired signals located atthe stations or floors may be employed, as illustrated in Figs. 1 to 10,inclusive, and also in Fig. 15, which illustrates two movable partsmounted on a fixed support or stud co-acting with two pairs ofterminals, one pair for each of two circuits.

As shown there are eight switch devices A20 A21, A22 x23 A24, A25, A26 dA21 t of each being mounted on each of the sliding bars or controllers,U, U, U and U",-as for instance, switch devices A and A" are mounted onbar or controller U, devices A and A on controller U, and so on. Thesecontrollers are mounted in'bars Y, Y which are secured to frame F of theapparatus. As only one signal device is to be operated in each car, eachswitch device is provided with but one pair of terminals, as a, a, a, a,a, a, a" and a", respectively, as soon. To co-act with each pair ofterminals and close the same, there is a movably mounted lever or part,as V, V, V, V, &c., each lever being preferably provided with insulatingmaterial at its co-acting end. as 1', 1", r. W, &c., and is mounted on astud or support, as a, w, v, a", &c., respectively, which studs orsupports are, as shown, in turn mounted fixedly in bars U, U, l and U,studs '0 and t" being mounted in bar [I studs 1) and 'v in bar U, studs'0, and o in bar U and studs '0 and o in bar U.

There are two carria es, B and B,

mounted to move back an forth in front of 5 sliding bars or controllers,as U, U, &c., in co-act1ng relations with movably mounted levers orparts, as V, V, &c., which may be connected with the car actuatingmechanisms as carria es B and B are shown to be connected or ot erwise,as desired.

The car with which actuating device or carriage B ma connect isdiagrammatically re resen at H and is provided with signal evice G, andthe car with which 5 actuating device or carriage B ma connect islikewise represented at H an is provided with signal device G. CarriageB, through surface E, co-acts with movably mounted parts or levers V andV, as it moves upwardly and throu h surface E, with levers or parts Vand as it moves downwardly, and carriage B, throu h surface E", co-actswith levers or parts and V, as itmoves upwardly, and, throu h sur- 215face E", co-acts with levers or arts and V, as it moves downwardly. achof these levers or parts, as V, V, &c., is preferably provided with atwo arm spring as d, Fi 13 and d", Fig. 12 of the drawings, whic 80 acton said levers or parts as springs d and of Figs. 7 and 9 act, aprojection or pin, as 0, Fig. 13 on each of the levers and a fixed studor projection, as d, attached to bar U, Fig. 12, coacting therewith, as001'- 85 responding projections c and d coact with 'sprmgdin igs.7and9.I,

As shown in Figs. 11 and 12 surface E, of carriage B has after coactingwith movably mounted part or lever V and cl 40 terminals a" of switchdevice A", 25 entirely by such lever so as to permit its two arm springd" to act and return'the lever to its normal position thereby oterminals a" again, and incline sur ace X,

(mounted on carriage B) has engaged with surface or roller 0: attachedto controller U, moving it against the stress of spring u until stop u"v on armature m has enga with rojection u attached to contro er U. becontroller U when in this position retains or holds the switch devicesA" an A" in position so that the movable levers or parts V and V do notclose the terminals of their respective switch devices until suchdevices and their circuits are brought into an o erable condition againby the person desiring to signal the car using the means provided forthis purpose. Carriage B has mounted thereon two movable inclinedabutting surfaces X and X and carriage B has two similarly mountedsurfaces X and X. These surfaces are held against turning in onedirection by pins {351' and 3 respectively and are norma y el in contactwith such pins by springs 31, y, y and 3 respectively, which yield andrmit these inclined surfaces to assume ositions corresponding to that inwhich sur ace X, of carriage B,

is shown in, when passin roller or surface :0 on controller U, while t ecarriage is moving downwardly and such controller is in position for itsswitch devices to be operated as either actuating device or carriage ismoving upwardly, as'shown. Surface E of carriage B in moving downwardlhas engaged with movable lever or part a and closed the pair ofterminals a and thereby closed the circuit to operate the singal G incar H, and such surface will hold such circuit closed so long as it isin contact therewith, as shown. When surface E has left or is justleaving lever or movable part V inclined surface X engages with rolleror surface 2 attached to controller U and moves it against the stress ofspring, not shown, until it is in the position controller U is seen tooccupy in Fig. 11, where armature m of magnet M" has engaged therewith,so as to retain the controller in position where the circuits connectedtherewith will be" in an inoperable condition, until armature m" isattracted by energizing magnet M. This may be done by any convenientmeans such for instance, as a source of energy, as S, push button P andcircuit wires 103, 104 and 105. All of the other magnets M", M and M areshown as being similarly energized. Magnet M" is connected with source Sand push button P" by wires 100, 101 and 102. Magnets M" and M areconnected with source S and push button P and P", res ectively, by Wires106, 107, 108, 109, 110 an 111, respectively, as shown. Signal device Gis connected with switch devices A and A" to give signals as carriage Bmoves upwardly and with devices A" and A" to 've signals as the carriagemoves downwar ly. Signal device G is connected with switch devices A andA to give signals as carriage B moves upwardly and with devices A and Ato give signals as it moves downwardly. Only one signal device is emloyed in each car for giving the up an down signals, the signals beinggiven as the car approaches the floors or stations, in both directionsof movement thereof.

The circuit for signal device G is from source S' by wire 112, thence bywire 113 to one terminal of each of the up switch devices A and A" andthence by the other terminal of each of these devices and wire 115 tothe other side of source S, for the up signals; and for the down signalsthe circult is from S by wire 112 to signal device G thence by wire 113to wire 114 and one terminal of the down switch A and thence by theother terminal of such device and wire 115 to the other side of source Sand also from wire 118 to wire 122 and then 30 to one terminal of deviceA and thence by the other terminal wire 123 and to wire and source S".

The circuit for signal device G is from source S by wire 116 to suchdevice, thence by wire 117 to one terminal of the switch device A andthence by the other terminal of such device and wire 118 to the otherside of source S and also from such device Gr by wires 11? and 119 toone terminal of switch device A and by the other terminal of that switchdevice and wire 120 to wire 118 and the other side of source 5*. Theseare the circuits for the up signals for car H and for the down signalsof this car the circuits are by Wires 116, 117 and 119 to one terminalof each of the switch devices A and A, thence by the other terminal ofsuch switch device and wire 118 to the other side of source S.

In the operation of giving the signal, when the carriage is movingdownwardly, as indicated in Fig. 11, (where carriage B is thus shown,)the magnet M is energized by operating push button P releasingcontroller U from the holding action of armature m. and permitting thestress of spring, not shown, to move such controller into the positionshown, bringing the switch devices A and A, controlled thereby, into anoperable condition. Then on the downward movement of carriage B thecoacting portion E, thereof engages with the adjacent end of the leveror movable part V moving it on its pivot or stud '0 bringing itsopposite end, having insulating material 1' into contact with thenearest one of the pair of terminals a, closing the circuit therethroaghand causing signal device G to operate and to continue in operation aslong as this coacting portion or part E of carriage B holds lever V inthe position shown in Fig. 11. and portion E have reached the pointwhere such portion ends, then'or about then the inclined surface Xmounted on this carriage, will enga ewith roller :0 mounted oncontroller F] and, as the carriage continues its downward movement, theinciined surface X will force the controller U against the stress ofspring u, not shown, and restore the switch devices and the circuitsconnected therewith to an inoperable condition, in which they willremain until push button P is again operated. This operation is repeatedfor each signal to be given from the station or floor where magnet 11 issituated. and the same is energized. If an up signal is to be given atthis same station or floor then push button P will be energized andcontroller U and switch devices A and A will be moved into operableposition and the above operation in substance will be repeated, thecarriage moving upwardly instead of downlVhen the carriage B" wardly.The operation of the parts connected with each magnet and its pushbutton is substantially the same. The signal is given in the firstapproaching car and the parts are restored to position by the continuedmovement of the carriage, whether such carriage is moving upwardly ordownwardly, accordingly as the up or down devices are brought intooperable condition by operating their respective push buttons.

If desired the controllers, as U, U, &c., may be made to support orcarry only one terminal of the circuit with which each switch device isconnected, as indicated in Fig. 14, where a portion of a controller, Uis shown to which is attached one terminal t of a switch device A. Theother terminal If is fixed to the bar U to which the lever or movablepart V is pivotally attached and consequently this lever and theterminal 6" of the air of terminals (4 do not move as the controllermoves in bringing the circuits into an operable condition and restoringthem to an inoperable condition. A spring a is connected with controllerU and the bar Y, so as to operate in connection with the armature m asspring a operates with armature m? of Figs. 11 and 12. 'hen controller Uis released by the movement of armature m the terminal t of switchdevices A is moved toward the right under the terminal t and then whenlever or movable part V is actuated by the upward movementof a carriage,as 13, having a coacting portion or part, as E, engaging therewithgerminul It will be moved downwardly and the circuit closed by thecontact of terminals 15 and t, and such circuit will remain closed untilcontroller U 8 is restored to the position seen in Fig. 11. \Vhen thismovable part or' lever V isnnoved by the upward movement of its coactingportion of the carriage asll", with the parts as shown in F ig. 1-1, theextent of movement of such lever will not cause terminal t to touchterminal t consequently the circuit remains in an in operable conditionuntil armature -m is operated.

Instead of using only a; single movable part or lever mounted on a fixedsupport, as shown in Figs. 11 and l2,two such levers or movable partsmay be so mounted, as shown in Fig. 15, where a section of a controller,as U, is provided with a switch device A" having two )airs of terminalsa and a". Two levers i and V similar to those seen in Figs. 11, 12 and13,-are pivotally mounted on a. stud a which is, as there shown, fixedlyattached to bar U. These levers or movable parts V and V are providedwith two arm springs 61*" and (1, respectively, which are arrangedin,con nection with pins it. (1. (1 and d", similar to pins J and d ofFig. '13, soas to llO operate as the corresponding levers or movableparts operate in Figs. 11, 12 and 13.

I have herein shown and described movable parts mounted on supportswhich are separate from that which supports the switch devices, or themovable portions thereof. The essential thing, so far as concerns themounting of these parts, is that each shall be so mounted that amovement may take place between such part and some portion of its switchdevice, whereby the operative relations between the two may be changedaccordingly as the switch device or devices are to be operated or not.The mountings of these niovablc parts herein shown will naturallysuggest others, to the minds of those skilled in the art, which willserve the same purposes in the same way that those shown do in thecombinations of devices or members hercin particularly pointed out, and,therefore, I desire that it be understood that this invention is notlimited to any specific form or c nstruction of movable parts or oftheir mountings or supports, but desire to include all that performessentially the same work in substantially the same manner in su heoinbinations'as these do which are herein shown. I have also shown anddescribed different forms or constructions of actuating devices ormeans, having both movable and immovable portions, which engage withsuch movable parts, as such devices or means more relatively thereto,and actuate the same. here the engaging port ons of such dcvicrs ormeans are movable in and out of operative position relatively to suchmovably mounted parts and means are i provided by which such portionsmay be thus moved or permitt d to move, such portion or portions andmeans may be of any desired form or construction, so long as the pa t,device or thing may be substituted for another and do the same work inany particular combination thereinafter pointed out in essentially thesame manner that the part, device or member hercin shown and deibeddocsits work. This isalso the case with the switch or contact devices,whether provided with movable parts or'portions or not. also with thecontrollers, terminals, retaining devices. or the means by which the niovablv part; of the switch and retaining devices mar be moved from oneposition to another in the operation of the apparatus.

The Form or construction of these several parts. members. means ordevices herein shown will sugge t oll c forms or construe liens to thoseskilled in the art. and, therefore, l wish to be understood as includingall terms roiislructiinis of equivalent character to that which isspecified in any given claim.
